Effect of Serum and Oxygen Concentration on Gene Expression and Secretion of Paracrine Factors by Mesenchymal Stem Cells

Figure 1

Normalized relative expression and secretion of paracrine factors under different oxygen and serum conditions. Data reported as mean ± SE. 5% and 20% refer to the amount of serum supplement present in the media. Open bars: secretion of factors into media. Solid bars: relative mRNA expression. (a) versus 20%, (b) versus normoxia.
